I used to hack Mega Man 4 but since it could not switch lots of graphics at a time, I chose to instead opt for MM5. Since MM5 present this advantage, I guess it has a disadvantage in consequence. But I cannot see : if I understand concepts correctly : http://datacrystal.romhacking.net/wiki/Mega_Man_V
It has mor chr_rom and even PGR_rom than MM4. So what is the catch? Also can someone tell me what other game use the same cartdridge as MM5 if I'd like to flash my hack on real cartdrige? |

That statement "kind of" in-correct.
MM4 is 512 kb, MM5 is 512 kb. Okay sure they're the same size, but the difference is. Megaman 4: all 512 kb is used by both graphics and programming space, they share the same 80,000 bytes. Megaman 5: 256 kb is used for programming space (the first 40,000 bytes) the 2nd 256 kb is for graphics space. They do "not" share the same space together unlike megaman 1, 2, 4, and 6. -------------------------- I dont know the answer to your last question though about other games, someone else probably will. |

Thanks a lot for this answer!! But what then explain that graphics can be switch in an instant in MM3 and MM5? I'm not sure I understand that point. The guess I could take is because MM5 has some space considered only graphics, it could load it instantly, where in MM4 for example, it would have to be "built", using scroll gfx, before loading it?
As a side question, I prefer MM3 like I talked to you, but I saw there would be some advantage with MM5 as MM3 had some glitches due to bad programming (being one of the first MMC3) (like stage select glitch) thanks for all the help, really appreciated |

Eh dont worry about glitches with mm3.
If you were to use "megaman 3 improvement 2.1" for the base of your mm3 hack, then there's no glitches period, almost ZERO lag/slowdown, a whole entire story intro which you'd be able to edit, and so much more. Megaman 5 is able to switch graphic pages on the fly instantly, megaman 3 does too because these games use CHR-ROM ....not CHR-RAM, just only need the following: LDA #graphic page number, STA $graphic banks E8 through ED, INC $1B" and that's it, nothing more. Megaman 4 is ridiculously complicated and long and i have no clue how it's done but it's horribly slow. But it's considered CHR-RAM. Along with megaman 1, 2, and 6. |
